File and Pay Business Taxes Online - Additional Information

Technical Notes

You must have a valid Missouri Tax Identification Number to file or pay using this system.
If you have not yet filed a registration application with the department, please visit the Business Tax Registration page.

Multiple file periods or billing notices can be filed/paid using this method; however, only one payment can be made for each filing period per day. (For example, a monthly sales tax filer can make payments for multiple months on the same day, but cannot make more than one payment for the same month on the same day.)

For the transactions listed below, the date you provide as the effective date is the “electronic” postmark date. If an effective date is not provided, the date the transaction was made will be considered the “electronic” postmark date and funds will be withdrawn within two working days of the effective date indicated. Payments can be made up to 45 days in advance. Payments can be cancelled by contacting the department on or before the effective date of payment by calling (573) 751-8150 or emailing [email protected]
